Hydrogen fluoride, HF exist as liquid at room temperature. Explain this phenomenon based on the formation of hydrogen bonds.​

Answers

Explanation:

The hydrogen fluoride molecule is highly polar, in the liquid and gaseous phases, HF prone to formation hydrogen bonds. ... These hydrogen bonds are strong, their energy is 41.5 kj/mol.

Hydrogen fluoride can be a liquid or gas at room temperature; it has a boiling point of 19.5 ºC. It is corrosive, colourless and has a very strong odour.The gaseous compound formed when dry fluorine gas reacts with dry Hydrogen, gas is called hydrogen fluoride. Hydrogen fluoride gas on condensation forms liquid hydrogen fluoride which is also referred to as anhydrous hydrogen fluoride or anhydrous hydrofluoric acid

Nitrogen dioxide gas is dark brown in color and remains in equilibrium with dinitrogen tetroxide gas, which is colorless.

2NO2(g) ⇌ N2O4(g)

When a light brown colored mixture of the two gases at equilibrium was moved from room temperature to a higher temperature, the mixture turned dark brown in color.

Which of the following conclusions about this equilibrium mixture is true?

This reaction is exothermic because the system shifted to the left on heating.
This reaction is exothermic because the system shifted to the right on heating.
This reaction is endothermic because the system shifted to the left on heating.
This reaction is endothermic because the system shifted to the right on heating.

Answers

Answer:

This reaction is exothermic because the system shifted to the left on heating.

Explanation:

2NO₂ (g) ⇌ N₂O₄(g)

Reactant => NO₂ (dark brown in color)

Product => N₂O₄ (colorless)

From the question given above, we were told that when the reaction at equilibrium was moved from room temperature to a higher temperature, the mixture turned dark brown in color.

This simply means that the reaction does not like heat. Hence the reaction is exothermic reaction.

Also, we can see that when the temperature was increased, the reaction turned dark brown in color indicating that the increase in the temperature favors the backward reaction (i.e the equilibrium shift to the left) as NO₂ which is the reactant is dark brown in color. This again indicates that the reaction is exothermic because an increase in the temperature of an exothermic reaction will shift the equilibrium position to the left.

Therefore, we can conclude that:

The reaction is exothermic because the system shifted to the left on heating.

The reaction is exothermic and the equilibrium position shifted to the left hand side.

An exothermic reaction is one in which heat is given out. Hence, the equilibrium position moves towards the left when the temperature is increased in an exothermic reaction.

Given the reaction, 2NO2(g) ⇌ N2O4(g) the appearance of a dark brown gas at high temperature implies that the reaction is exothermic and the equilibrium position shifted to the left hand side.

A gas has density 2.41 g/liter at 25°C and 770 mm Hg. Calculate it's molecular mass (R = 0.0821 L atm.mol-1K-1.

ASAP!!!!!!!!! ​

Answers

Answer:

Molecular mass, M = 58.20 g/mol.

Explanation:

Given the following data;

Density = 2.41 g/literTemperature = 25°CPressure = 770 mmHgGas constant, R = 0.0821 L atm.mol-1K-1

Conversion:

760 mmHg = 1 atm

770 mmHg = 770/760 = 1.0131 atm

Temperature = 25°C = 273 + 25 = 298 K

To find the molecular mass, we would use the ideal gas law equation (density version);

PM = dRT

Where;

P is the pressure.M is the molecular mass.d is the density of a substance.R is the ideal gas constant.T is the temperature.

Making M the subject of formula, we have;

[tex] M = \frac {dRT}{P} [/tex]

Substituting into the formula, we have;

[tex] M = \frac {2.41 * 0.0821 * 298}{1.0131} [/tex]

[tex] M = \frac {58.9626}{1.0131} [/tex]

Molecular mass, M = 58.20 g/mol.

A 15.8 g sample contains 3.60 g F, 4.90 g H, and 7.30 g C. What is the percent composition of hydrogen in this sample?

Answers

Answer: 22.7848% F or 23%

Explanation: %F = 3.6g/15.8g • 100% = 22.7848% F

The percentage composition of hydrogen in the given sample is equal to 31%.

What is percentage composition?

The percentage composition of a given compound can be described as the ratio of the quantity of each element to the total quantity of individual elements in the compound multiplied by 100. The quantity can be measured in terms of grams of the elements present in the sample.

The percent composition is expressed in its composition in terms of all the elements present. Thus, it helps in the chemical analysis of any given compound.

The percentage composition is expressed using the following formula,

Percentage composition of E = (E/T) × 100

Where E represents the total quantity of element E present in the compound and T represents the total quantity of all the elements present in the compound.

Given, the mass of the F, H, and C is 3.60g, 4,90 g, and 7.30 g respectively.

The total mass of the given sample = 15.8 g

The mass of the hydrogen in the sample = 4.90 g

The percent composition of H = (4.90/15.8) × 100 = 31 %

Therefore, the percent composition of hydrogen in this sample is 31%.

Answers

Answer:

Wavelength = 0.049 m

Explanation:

Given that,

The frequency of a wave,[tex]f=6.1\times 10^9\ Hz[/tex]

We need to find the wavelength of the wave. We know that,

[tex]c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{2.998 \times 10^8}{6.1\times 10^9}\\\\\lambda=0.049\ m[/tex]

So, the wavelength of the wave is 0.049 m.

If 1000. mL of water freezes, which of the following is a reasonable approximation for the volume of the resulting ice?

Group of answer choices

1000. mL

961 mL

1040 mL

Explanation:

Ice is fewer denser than water.

The reason is the volume occupied by the same mass of ice with water is more than the volume occupied by water. Ice has more empty space within it.

Due to this reason, ice floats on water.

When 1000ml of water freezes to ice then its volume is greater than water.

Among the given options the correct answer is 1040 mL .

How many mm of 0.200 M FeCl3 are needed to react with an excess of K2S to produce 2.75 g of Fe2S3 if the percent yield for the reaction is 65.0%?

Answers

Answer:

130 mL

Explanation:

2FeCl3(aq) + 3K2S(aq) -----> Fe2S3(s) + 6KCl(aq)

Percent yield = actual yield/theoretical yield × 100

actual yield = 2.75 g

Theoretical yield = x

65= 2.75/x × 100

x= 2.75 × 100/65

x= 4.2 g

Number of moles of FeCl3 = mass/molar mass = 4.2 g/ 162.2 g/mol = 0.026 moles

Then;

n= CV

n= number of moles

C= concentration

V= volume

V= n/C

V= 0.026 moles/ 0.200 M

V= 0.13 L or 130 mL
